A secret area is an optional location within some dungeons of World of Final Fantasy. These areas often contain exclusive Mirages or treasure, and are either off the main path or require some prerequisite to access them. The names of these areas often have "Secret" followed by the name of the areas in the dungeon (as shown when pulling up the map screen).
Most Mirages found in the secret areas are encountered on the field or inside Murkrifts, but for some, walking to otherwise empty spots triggers a cutscene and a battle is then initiated with them. Defeating the Mirage(s) often unlocks a memento that allows the player access to its transfiguration. Non-Murkrift enemies respawn when the player travels back to Nine Wood Hills and returns to Grymoire.
